Dissociation of dimeric vanadium(V) complexes with 8-quinolinol(Hox) and 4-isopropyltropolone(Hipt), V<SUB>2</SUB>O<SUB>3</SUB>(ox)<SUB>4</SUB> and V<SUB>2</SUB>O<SUB>3</SUB>(ipt)<SUB>4</SUB>, in organic solvents was studied spectrophotometrically. The equilibrium is found to be<BR>V_2O_3L_4+H_2O\rightleftarrows2VO_2L+2HL<BR>with the following logarithmic equilibrium constants: log<I>K</I>=−12.9 for L=ox<SUP>−</SUP> and −12.8 for L=ipt<SUP>−</SUP> in chlorobenzene. VO<SUB>2</SUB>L was synthesized and characterized by IR, UV, and visible spectroscopy for these ligands and also for 2-methyl-8-quinolinol.
